Well, yes. It has been 6-8 yrs since I have read any fortran code, but I believe arguments or parameters are not valid.

I would follow up on Corona688's suggestion of modifying the program to...

No. The shell will evaluate the variable $FILE and perform Variable Expansion to convert the variable into the actual filename.

If your program can handle arguments, the code would then use...

Assuming your fortan code can handle arguments...
for FILE in *.txt; do fortran_progname ${FILE}; done

Are you trying to rename the file ?? It has whitespace yes ??

Or do you just want the numerical value at the beginning of the file name ??

The OP asked about if a file exists...
However a file may exist, but NOT be a regular file...
So,

If I understand the OP correctly du -sh */ should give the desired results.
EDIT: (Maybe they only need TODAY's directories) Then I am wrong.

I admit I did miss the x100 files. That would make 10 Billion digits. But note that 3.14159265... is pi NOT phi 1.6180339887...

If you have 1 million lines of 'phi' and each line is 100 characters long, that is only 100 million digits of 'phi' not 10 billion

@ scottn: Thanks you are right. What I meant was this then.

@ oht: Just change the alias name from test to test_it like this:

alias test_it='echo 123\$acct54679abc'

:o

@ oht: Just change the variable name from test to test_it like this:
test_it='echo 123\$acct54679abc'

You can 'append' file(s) to a tarball, but unfortunately in your case, you have to 'gunzip' in order to add another file to the archive.

I know this post is 4 days old and you may have figured it...

If I understand you correctly, you want a script that will search for filenames with a pretext and a numerical value, and you want to find the given pretext with the largest numerical value?

@ Alister: Thanks for the correction.

Doesn't seem right, the man page for 'sed' states that the option -e adds a script to the command(s), and hence should be a [space] after -e .

I also think you may need to escape each '*' with a...

The history command in 'ksh' is actually an alias to hist -l.

Use the syntax as such:
hist -l 1 999Where [1] is the first line of your history, and [999] is the last line of history you are...

'umask' is a subtractive value, so files and directories are evaluated differently.
umask 000; touch filename.txt
will have a octal value of 666 and,
umask 000; mkdir new_directory
will have an...

Take a look at this thread (https://www.unix.com/shell-programming-scripting/157740-howto-get-only-filename-find-command-linux.html).

Using find will output filenames only for all files modified not only within the last 24 hours, but all files modified today and from the beginning (midnight) of yesterday.

No need to 'touch' a...

ahamed101's script works for me in bash, what is your OS and what is your shell?

Here (https://www.unix.com/shell-programming-scripting/156949-file-size-mb.html) is a good thread to get filesizes.

Thanks to all who posted, you really showed me some new ways to use awk! (Always learning.)
